! The external trigger event occurs to timeslot 3 on DSS1, timeslot 3 on DSS2 and timeslot 2 on DSS 3-5. 

Note1

This command sets/queries the DTS parameters for one or several DSSs. In the setting form, the first two parameters in the command indicate the first and last sequence step to which the following parameters apply. The subsequent parameters are specified as an array of values, where each element of the array correspond to a DSS. The test set compensates by using the value of the last element in the array when there are too few elements and by ignoring settings if there are too many elements in the array. In the querying form, the first parameter indicates the result of which sequence step is returned and the second parameter is omitted. You can only query the DTS parameters for one DSS at a time.

Note2

This command sets/queries the DTS parameters on a per DTS basis. The parameters in the command are specified as an array of values, where each element of the array corresponds to a DSS. The number of elements that should be specified in the array is given by the DTS Step Count . If these numbers contradict (that is, the DTS Step Count does not equal the number of array elements specified for the array), the test set compensates by using the value of the last element in the array when there are too few elements and by ignoring settings if there are too many elements in the array.
